libnsl.so.1: cannot open shared object file: No such file or directory

Symptoms:

Installed the Oracle InstantClient on Linux Linux 8 (packages instantclient-basic-linux.x64-19.11.0.0.0dbru.zip and instantclient-sqlplus-linux.x64-19.11.0.0.0dbru.zip) and later configured the environment variables:
export ORACLE_HOME=/u01/instantclient_19_11/
export LD_LIBRARY_PATH=$ORACLE_HOME
export TNS_ADMIN=/u01/instantclient_19_11/network/admin
export PATH=$ORACLE_HOME:$PATH

When calling the sqlplus utilitary, it presents an error regarding Linux packages missing with message:
sqlplus: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory.

Cause: 

SqlPlus uses a few linux libraries and one of that is exactly the libnsl.
However there are a few packages with similar names (or endings) that does not solve the issue.

Solution:

Simply install the package libnsl with command:
yum install libnsl -y
